Original Product of the Renowned Company Etanco®
Additional significant anti-corrosion protection and a perfect match to the RAL/NCS color. UV stabilizers ensure color consistency even after several years, and the modern Powder.coat powder coating technology ensures the durability of the coating during installation and a long service life.
2. EPDM washer
Made of the best sealing material - EPDM. It does not lose elasticity over time and has a very long aging period. Resistant to changing weather conditions and UV radiation. After installation, it self-vulcanizes to the sheet metal, creating a tight connection.
3. Hexagonal head with marking
The hexagonal head ensures easy and secure screw installation, which significantly simplifies work and increases installation efficiency. The distinctive marking of ETANCO products allows for easy identification; each production batch is assigned a unique number, enabling precise identification.
4. Thread under the screw head
The additional thread with an increased diameter ensures proper distribution of the EPDM washer on the thin cladding sheets of the sandwich panel.
5. GREY.COAT ceramic coating
Provides the highest protection against corrosion while maintaining excellent drillability. This allows them to be used in demanding conditions, such as a C4 corrosive environment.
6. Self-tapping tip (double thread)
Specially designed drilling point combined with the Hi-Lo thread enables direct installation in wood and concrete (in the case of concrete, a 5 mm diameter hole must first be made).
In combination with the ULTRA expansion sleeve, installation is possible in materials such as solid brick, ceramic brick, perforated brick, aerated concrete.
Designed for attaching sandwich panels to solid materials such as wood, concrete, aerated concrete, brick.
